I wish mlb would bring all the cricket tech.
The audio meter thing is wiiiiild. (Where they use high precision microphones to determine if the ball made contact with the bat).
Also there’s no excuse for not having full 360 3D representative video for each base. Having some sort of pressure sensor would be useful too.
Better safety features would be useful (like better face protection like the cricket steel grill).
And just more damn cameras for all the edges (like home run or foul lines).
